This is my first post, so "Hello everyone!,"
Would love for the electrically talented to chime in...
I was given an Earthwise 60120 Cordless Mower (24v, 20a) the other day and I'm trying to figure out the issue with it. It was supposedly purchased last year, used last summer, stored over winter in a comfortable garage (I'm presuming possibly without charging the batteries every 30 days or so), and then the previous owner attempted to operate it but stated that they couldn't get it "to take a charge" so they bought a new mower and gave this nearly new one to me.
I have attempted to charge the mower and the charger seems to be functioning well--one light on charger indicates power to the charger and another light indicates charging/full-charge of battery. It has several green lights on the back of the mower and a red light that signifies that it's super low and needs to be charged. Once the charger's indicator light turned green, I then checked the voltage with a multi-meter using the contacts on the battery plug and it read 26.28 volts. I have read in another thread that it's supposed to be closer to 31 volts when completely charged....does that sound right? The charger puts out 31 volts, going by a multi-meter reading.
When I went to run the mower, it either spins up and shows a red light on the back of the mower or spins up and doesn't (I might be confused, but that's how it seemed). It sounds like the motor and blade spun up to speed as it should, but then the charge diminished rapidly (within 1 minute of mowing grass that had been cut two days ago by a gas mower...little resistance on the blades or load on the motor). Additionally, I pulled the handle to start the mower and handful of times to see if there was much power and the motor spinning sounded great at first, then another pull and the spinning was much slower....another pull about the same....another pull full speed....then slow...slow...dead. Lol. I'm charging it again and will double check what I just wrote about the light and power.
I have yet to take it apart to check out all of the electrical or to check the motor resistance (still unsure how to check resistance). I have read that it might very well be that the "rectifier" (or possibly rectifier and motor?) that might be the culprit.
Any help would be greatly appreciated!
Thanks,
Steve
